DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device for viewing information on a server via a line, such as a browser for viewing a homepage on the Internet, at a terminal. It has a characteristic in taking in.

[0002]

2. Description of the Related Art The structure of the WWW of the Internet in a conventional display device and the function of a browser for reading the WWW will be described.

In FIG. 3, reference numeral 301 denotes a user terminal;
2 is a telephone line, 303 to 306 are servers, and is a block diagram schematically showing a connection relationship between a terminal and each server. A terminal 301 at home or the like is connected to a server A 303 called a provider via a telephone line 302. Server A303 is a server B304 around the world
-Directly or indirectly connected to the server D306.

[0004] On the terminal 301, information called a home page in each server can be viewed. As a connection procedure, a call is made from the terminal 301 and the telephone line 302
Is connected to the server A 303 via the. Next, the terminal 301
URL of required information from Uniform Resou
loc Locator: address). UR
L includes a server name section 401, a directory name section 402, and a file name section 403, as shown in FIG. That is, the URL is represented by an HTML file. The server A303 that has received the URL sends this URL and its own server name to all servers, and sends the server name 4 in the URL.
The server having the name that matches 01 sends an HTML file that matches the file name 403 in its own directory name 402 to the server A 303 that has made the request. Upon receiving this, the server A 303 sends the HTML file to the terminal 301 via the telephone line 302.

The HTML file sent at this time has the contents shown in FIG. Character information 501 is characters displayed on the screen of terminal 301. The image information 502 is stored in the terminal 30
Although it is information related to an image displayed on one screen, it is not the image data itself but a URL with the image data. Therefore, when displaying the HTML file on the screen of the terminal 301, the file containing the image data body is read in the same procedure as described above, and the image is displayed at a predetermined position along with the characters. Next, the link information 503 is information on a URL of a jump destination when the user selects this. There are two types of link information 503. One is
This is the page that shows the contents of the page you are looking at, that is, the table of contents, which is usually located in the same directory on the same server or in a directory below it. The other is a page created by someone else related to the page you are looking at, ie a bibliography, usually on a different server or in a different directory. However, the formal treatment of these two types is exactly the same, and when the user selects, the U
The HTML file of the RL is read and is newly displayed.

HTM commonly used on the Internet
L (Hyper Text Markup Langu)
FIG. 6 shows an example of an HTML file described in “age).
FIG. 7 shows a display screen of the terminal 301 based on this. Reference numeral 601 denotes character information, and the content described here is displayed on the screen of the terminal 301 as it is. However, <BR> represents a line feed. The character information 601 to 603 is displayed at 701 in FIG. Image information 604
Indicates the location of the image data following the IMG SRC =. According to 604, the directory "saturn. j
The image data named pg is read, and the image is displayed on the screen of the terminal 301 as indicated by 702. Link information 606, 607, 609 to 611 are A HREF
Is a URL of another page following the =, characters written between this and </A> are displayed on the screen of the terminal 301 with an underline as shown at 705, and the user If you click on this part, the H in that URL
The HTML file is read, and the entire screen of the terminal 301 is rewritten based on the new HTML file content. Here, in the link information, a server name and a directory are omitted in 606, but the ring information is stored in the same directory on the same server as the original file. htm
1 means that a file is included. Also,
The link information 607 is stored in a directory named moon under the same directory / saturn / data of the same server B as titan. html.

On the other hand, link information 609 to 611
Refers to a file on another server or another directory. 606,607 and 609-6
11 is different in the location of the file, but is the same in that when the user specifies it, a new HTML file is read and the display is rewritten.

The processing contents of the display device for realizing the above will be described with reference to FIG. FIG. 2 is a functional block diagram of a conventional display device. The HTML analysis processing unit 102
03, a data determination unit, 104, a text processing unit, 105
, An image data processing unit 106, and a link information processing unit 106. The HTML file from the telephone line is read by the data determination unit 10 in the HTML analysis processing unit 102 via the reading unit 101.
Sent to 3. Here, the character information, the image information, and the link information in the HTML file are discriminated, and are sent to the text processing unit 104, the image data processing unit 105, and the link information processing unit 106 to perform each processing. The text processing unit 104 arranges the text data and arranges the
07. The image data processing unit 105 instructs the reading unit 101 to read the image data from the server in which the image data is actually stored, and when the actual image data is sent, displays the image data on the display unit 107. The link information processing unit 106 displays the link portion on the screen on the display unit 107 so that the user can recognize the link portion, and also transmits the link destination address to the operation unit 108. The user operates the operation unit 1

Instruct 01.

[0009]

According to the above prior art, there is a problem that it takes time to open the next page because the user starts reading after designating the link destination. That is, although all data is sent through a telephone line, the data transfer speed of the telephone line is slow, and it takes a very long time to read large data such as image data. Also, each server is often called busy from all over the world, and the time spent in the queue may be quite long. For this reason, it takes a considerable amount of time to call the HTML file and the image data included in the HTML file after specifying the reading destination, which may be frustrating for the user.

When a page contains long character information, the user takes time to read the information. At this time, even though no data is flowing through the telephone line, the line is not used. Because it stays connected,
During that time, there is also a problem that call charges are added and the line charges increase.

It is an object of the present invention to display the next page without waiting for the user when switching pages, to provide a suitable operation environment, and to reduce the line usage fee.

[0012]

In order to solve the above-mentioned problems, a display device of the present invention allows a user to read the contents of a link corresponding to the page content among the links of the current disclosure page by reading the current page. This is stored in advance in the storage unit using the time during which the data is stored, and when there is an instruction to move the page, this is read out from the storage unit and displayed at high speed. Also, after reading out all necessary parts, the telephone line is cut off to reduce the line usage fee.

According to the present invention, it is possible to provide a display device capable of realizing high-speed movement from a disclosure page to a link destination page and reduction of a line usage fee.

(Embodiment) An embodiment of the present invention described in claims 1 to 5 of the present invention will be described below with reference to FIG.

FIG. 1 is a functional block diagram of a display device according to an embodiment of the present invention. The difference from FIG. 2 is that a current address recognition unit 109, a link address recognition unit 111, a comparison unit 110 are added to the link information processing unit 106, and a storage unit 112 is added.

When a certain page is opened, the HTML file from the telephone line is sent to the data determination unit 103 in the HTML analysis processing unit 102 via the reading unit 101. The data determination unit 103 determines the character information, image information, and link information in the HTML file, and sends the information to the text processing unit 104, the image data processing unit 105, and the link information processing unit 106 that perform the respective processes. . The text processing unit 104 arranges the text data and arranges the text data.
7 is displayed. The image data processing unit 105 instructs the reading unit 101 to read the image data from the server in which the image data is actually stored, and displays the actual image data on the display unit 107 when it is sent. The link information processing unit 106 displays the link portion on the screen on the display unit 107 so that the user can recognize the link portion, and also transmits the link destination address to the operation unit 108.

After displaying all the pages currently open on the display unit 107, the following processing which is a feature of the present invention is performed. The link information processing unit 106 recognizes the server name and the directory name of the page currently opened by the current address recognition unit 109. For example, if the currently open address is as shown in FIG. 4, the server name is serverB at the beginning and the directory name is / saturn / data up to the file name. Next, each time link information is sent, the link address recognition unit 111 recognizes the server name and directory of the link destination. For example, in 606 of FIG. 6, since the server name and directory are omitted, it is recognized that this is the same as the server name and directory of the currently opened page. The comparison unit 110 compares these,
In this case, since the server name and the directory name are the same, the reading unit 101 is instructed to take in the file indicated by 606. The fetched file is sent from the reading unit 101 to the data determining unit 103, and an instruction is given to the reading unit 101 to extract the image information and read it again.
The file indicated by reference numeral 606 and the image file necessary for the file are stored in the storage unit 112 together.

With respect to 607 in FIG. 6, in the link address recognition unit 111, the server name is serverB and the directory name is / saturn / data / m.
oon. Since the currently opened page and the server are the same and the directory is below the current page, this is also read similarly to 606 and stored in the storage unit 112.

For 609 to 611 in FIG. 6, no reading operation is performed because the current disclosure page and the server name or directory name are different. Thus, the comparison unit 1
In step 10, the link information is read from the same server as that of the currently opened page and image information relating to the file in the same or lower directory position as the opened page, and is read into the storage unit 112. This is an instruction to memorize.

Normally, the time during which the link information is being read is the time during which the user is reading the currently open page. That is, in the related art, the line is connected but the data is not moved, but the display device of the present invention uses this time to read the information on the next link.

After the user reads necessary information on the current disclosure page and specifies to move to the link destination by using the operation unit 108, the specified link information becomes 606 to 60.
If the information is already stored in the storage unit 112 as shown in FIG. 7, the information is sent from the storage unit 112 to the display unit 107 and displayed. At the same time, the newly opened page content is sent to the data determination unit 103, and among the link information contained therein, the file in the same directory on the same server or in the lower directory is read in the same manner as the above procedure,
The information is stored in the storage unit 112.

According to the above procedure, the data reception waiting time when moving to the next link destination can be shortened.

Next, an embodiment capable of reducing the line usage fee will be described. An actual homepage is, for example, a single book, and a user often reads almost the entire homepage. Therefore, when reading a certain homepage, the phone line is cut off after all the information constituting the page is fetched at a stretch, and the phone line is cut off while the user is actually reading each page. In addition, the line usage fee can be minimized.

At this time, the processing when the main page is opened basically performs the same processing as described above. That is, the HTML file from the telephone line is transmitted to the HT via the reading unit 101.
The data is sent to the data determination unit 103 in the ML analysis processing unit. Here, text information, image data processing section 105, and link information processing section 1 which determine the character information, image information, and link information in the file and perform the respective processes.
06. The text processing unit 104 displays the text data side by side on the display unit 107. The image data processing unit 105 instructs the reading unit 101 to read the image data from the server in which the image data is actually stored,
When the actual image data is sent, it is displayed on the display unit 10.
7 is displayed. The link information processing unit 106 displays the link portion on the screen on the display unit 107 so that the user can recognize the link portion, and also transmits the link destination address to the operation unit 108.

After all the pages currently open on the display unit 107 are displayed, a message as to whether or not to perform the line blocking processing of the present invention is displayed on the display unit 107 to confirm with the user. The reason for confirming at this stage is that, in a general usage, only the cover of the home page is looked at, and if the content is different from the expected one, it is immediately moved to another page. This is because fetching the lower page immediately may be useless. When the user designates not to perform the line blocking processing on the operation unit 108, as in the related art, the user waits without doing anything until the user designates the next link destination. When the user specifies to perform the line disconnection process, the telephone line is disconnected after all relevant information is taken into the storage unit 112 in the following procedure.

The current address recognition section 109 recognizes the server name and directory name of the current disclosure page. Next, with respect to all the link information in the main page, the link address recognition unit 111 recognizes the server name and the directory of the link destination. The comparing unit 110 compares them, and if the server is determined to be located in the same server and in the same or lower directory, the reading unit 10
1 is instructed to take in the file. The fetched file is sent from the reading unit 101 to the data determining unit 103. The reading unit 101 instructs the reading unit 101 to extract the image information and read it again, and stores the file together with the image file necessary for the file. The information is stored in the unit 112.

In the above example, only the page one level below the currently displayed page is read and stored. However, in this example, all files including the link file further below are read. That is, the link information included in the file is also sent to the link information processing unit 106, and similarly, the link information located on the same server as the current disclosure page and in the same or lower directory is imported to the reading unit 101. The read file is sent from the reading unit 101 to the data determination unit 103, and the reading unit 101 extracts the image information and reads it again.
Is stored in the storage unit 112 together with the file and an image file required for the file. By repeating this, all the files in the lower directories linked in a chain from the currently open page are read and stored in the storage unit 112, and thereafter the telephone line is cut off. When the user specifies a link destination, if the link is a link stored in the storage unit 112, the link is read out from the storage unit 112 and displayed on the display unit 107, and is not stored in the storage unit 112. If it is a link, the telephone line is reconnected, and reading is performed again according to the above procedure.

Here, if the user specifies a link destination before saving all the data in the storage unit 112 and the link file is not yet stored in the storage unit 112, the reading of the file currently being read is performed. Is temporarily interrupted, the specified link file is read with priority, and is directly displayed on the display unit 107, and then reading of the interrupted file is resumed. In addition, by setting the priority of reading a linked file so that a file directly linked to the currently open file is read prior to a file linked indirectly below the file,
The possibility of such an interruption can be reduced.

[0034]

As described above, according to the display device of the present invention, since the information file of the linked information page is stored on the disk in the terminal, the movement between the links can be performed at high speed. become able to. In addition, by collecting necessary information files all together and disconnecting the telephone line, the line usage fee can be reduced.
